Subject: [PATCH] serial: atmel: honor CREAD in atmel_set_termios
Date: Fri, 1 May 2026 13:43:17 +0530 [thread overview]
Message-ID: <20260501081317.15477-1-alasyamrakesh77@gmail.com> (raw)
Ignore received characters when CREAD is cleared by adding RXRDY
to ignore_status_mask.
This replaces an existing TODO in the driver.
